  1. Introduce a PI OPC UA Server

    The OPC landscape is shifting away from DA/HDA and towards UA servers. A significant number of OPC client tools are being created that connect to OPC UA servers, and none of these are compatible with PI without the use of a third party UA wrapper since we only provide DA and HDA servers.

    We have been gathering use cases and information about OPC UA Server functionality as it pertains to OSIsoft products.

    There are a number of different requirements to consider, and as such we’re changing the status back to “UNDER REVIEW / RESEARCHING” to more accurately reflect the current status of the work.

    At this time, we are not committing to bringing this capability to market.

    We will update this thread if the status changes.

  2. Windows authentication of clients

    As a PI user, I want the OPC DA and HDA Servers to honor the Windows identity of any connected OPC client.

    We understand the requirement. It makes sense. We have been looking into it but it turns out to be difficult to do. We used a third-party framework to build the PI OPC DA Server which separates interactions with the OPC client from interactions with the PI Data Archive. It solved a number of problems but unfortunately there is no easy way to have OPC client user credentials flow to the PI Data Archive. We are evaluating our options.
